1'0 (LZZ whom it may concern.-

Be it known that I, FRANK B. FARGO, of Lake Mills, in the county of Jefferson and State of Visconsin, have invented a new and usefulImprovement in a Combined Churn and Butter-Yorker, of which thefollowing is a description, reference being had to the accompanyingdrawings, which are a part of this specification.

My invention relates to improvements in machines adapted to be used, incertain changed relations of the parts, both asa churn and as abutter-worker.

The invention is particularly adapted to a machine which in its generalfeatures is substantially like the one for which an application, SerialNo. 561,712, for a patent has heretofore been'made.

The invention consists of the devices and mechanism hereinafterdescribed and claimed or their equivalents.

In the drawings, Figure 1 is a central longitudinal section of the drumand principal parts of the machine, exhibiting some of the features ofmy invention therewith. Fig. is an elevation of the rear end of themachine. Fig. 3 is a transverse section of the drum and parts therein online 3 3 of Fig. 1, looking toward the right. Fig. 4 is a transversesection on line 4; 4: of Fig. 1, looking toward the left. Figs. 5 and 6are respectively a front and edge view of parts at the rear end of thedrum shown in place in Fig. 3. Fig. 7 is a transverse section on line 77 of Fig. 5. Fig. 8 is a front view of parts at the front end of thedrum shown in place in Fig. 4. Fig. 9 is a transverse section on line 09 of Fig. 8.

In the drawings, A is a frame of suitable size and form to support theoperative mechanism.

B is a cylindrical drum adapted to hold the material, either milk orbutter, to be operated on. The drum is provided with a door 0 in itsperiphery, through which the material to be operated on can be put intothe drum and its product removed therefrom.

The front head of the drum is provided with a central aperture ofconsiderable diameter, in which a hollow annular gudgeon 10 is insertedaxially an d is secured to the drumhead liquid-tight. The gudgeon hasitsbearings on the frame A. The rear head of the drum is provided with anenlarged annular gudgeon provided with a radially outwardlyextendingflange 12 and a radially inwardlyextending flange 13, provided centrallywith an aperture and a short tubular member 14 thereabout. The tubularmember 14: is inserted in and partially through the rear head of thedrum, axially thereof, and the flanges 12 and 13 bear against the outersurface of the head of the drum, the flange 12 serving as a means forattaching the gudgeon 11 securely to the drum.

At the front end of the drum a partial head 15 is provided, which fitsloosely against the inner end of the gudgeon 10 and is arranged to beclamped thereto liquid-tight on an interposed gasket by means of a link16, an eccentric 17, and a spider 18, which spider rests loosely in andagainst the outer end of the gudgeon 10. Within the drum there are twopreferably corrugated and mismatched rollers 19 19 substantially as longas the interior of the drum, which at their front ends are provided withjournals that pass through the partial head 15 and are mounted revolublyin the spider 18, through which they pass and carry thereon a cross-bar20, which is provided with a medial hub 21, concentric with the axis ofthe drum. At the rear end these rollers 19 are journaled in a cross-head22, which is provided medially with an arbor 23, which projects throughthe rear head of the drum and has its bearings in an adjustable part ofthe frame hereinafter specifically described. A gland 24 is providedwhich is secured releasably and adjustably to the flange 13, which, withthe tubular member 11 and an interior portion of the head of the drum,forms a stuffing-box about the arbor 23, where it passes through thehead and the tubular member 14-.

For conveniently centering the arbor 23 in the drum and adjusting it onthe frame with reference to other parts of the mechanism and forproviding for taking up wear of the parts a frame member 25 is providedwhich is clamped to and is adjustable vertically in ways therefor on theframe conveniently by means of the bolt 26, fixed in the frame andprojecting through a longitudinal slot 27 therefor in the member Thearbor 23 has its j ournalbearing in this member 25, being thus mountedadjustably vertically on the frame and concentrically with the drum. Thegudgeon 11 is supported on the main frame A, bearing directly againstsegmental Babbitt blocks 28, which are socketed in the frame an d enteran annular groove therefor in the gudgeon 11.

The hub 21 on the cross-head 20 is provided with a sprocket-wheel and isconnected operatively, by the sprocketchain 29, the counter-shaft 30,and the sprocket-chain 31, to the arbor 23, whereby concurrent motion iscommunicated to the cross-heads 20 and 22, thereby compelling thehomogeneous whirling or revolving of the rollers 19 about the axis ofthe drum. This movement is enr ployed when the machine is used as achurn, at which time the partial head 15 is clamped firmly to the drumand revolves therewith, carrying the rollers 19 around with it and thedrum.

The drum is provided with a ring-gear 32, rigid on its front head, byand through which it is rotated by means of gear from the driving-pulley33, and the rollers 19 are also geared to the shaft of the pulley 33 andare rotated on their own axes therefrom when the machine is used as abutter-worker. The gearing connecting the pulley 33 operatively to thedrum and to the rollers 19 is not shown in detail, as it forms no partof the present invention.

Much trouble has heretofore been found in 9 so constructing andarranging the rollers in devised and use devices of new and peculiarconstruction adapted to overcome the difficulty heretofore experienced,which devices are preferably substantially of the following character:At the front end of the drum a U shaped bracket 34:, Figs. 8 and 9, isprovided, which is secured rigidly to the partial head 15 in suchposition as to be directly above the ends of the rollers 19 when themachine is employed as a butter-worker and while the rollers are held inplace against revolution about the axis of the drum. This bracket 34; issecured to the head 15, preferably, by bolts 35 35. The bracket isprovided with an elongated ledge 36, somewhat curved at its lower edgeto correspond with and fit close over the ends of the rollers 19, whichledge projects from the body of the bracket into the chamber of the drumsuificiently far to cover the spaces or joints between the ends of therollers and the partial head 15, so as thereby to catch any strayparticles of butter and thereby prevent them from getting into thejoints between the ends of the rollers and the partial head 15. Sockets37 37 are also provided on this bracket for receiving and holdingtherein the ends of the hopper-bars 38. Above these sockets 37 I providebearing-surfaces 39 39, inclined and extending inwardlydownwardly,adapted to receive thereon and support the hopper-plate 40, whichhopper-plate is adapted to receive thereon falling lumps or masses ofbutter and carry them inwardly downwardly onto the rollers at somedistance from their extremities. Flanges 41 ll alongside thebearing-surfaces 39 39 fit against and cover the ends of thehopper-plate 40 and provide a bearing for it against longitudinaldisplacement.

At the rear end of the drum a U-shaped bracket 42, Figs. 5 and G, isprovided, which is an elongation of whathas hereinbefore been called thecross-head 22. This bracket and cross-head are provided withinwardlyprojecting ledges 43, approximately like the ledge 36 andadapted at the rear end of the machine to catch and carry particles ofbutter away from the journal-bearings. This bracket 42 is also providedwith sockets 44, adapted to receive and hold therein the hopper-bars 38.Above these sockets there are inclined bearing-surfaces 45,substantially like the bearing-surfaces 39 39 at the front end of thedrum, which bearing-surfaces 45 are adapted to receive and hold thehopperplate 46, which hopper-plate is adapted to receive thereon lumpsor masses of butter and carry them downwardly away from the spacesbetween the ends of the rollers and the drumhead onto the rollers.Flanges a7 47 on the bracket alongside the bearing-surfaces 45 fitagainst and partially cover the ends of the hopper-plate :t6 and preventits displacement endwise.

Notwithstanding the provisions made for protecting the journal-bearingsfrom getting butter or foreign matter therein and for grinding it anddischarging it in blackened particles into the butter there is stilldanger that this will sometimes occur, and to obviate this trouble,especially when the machine is being used as a butter-worker, I providedripcups 48 4:3, which are secured to the bracket 42 immediately belowthe inner ends of the roller journal-bearings therein to catch anydischarge of residuum or foreign matter therefrom and prevent itsgetting into the butter. It will be observed that these are locatedimmediately below the journal-bearings when the mechanism is in positionfor working butter and are therefore satisfactory for the purpose forwhich they are intended during the process of butter-working. After thebutterworking and when the drum is being washed out these drip-cups willbe cleaned by the swashing of the water. Of course these dripcups arenot available when the machine is being used as a churn; but there islittle danger of objectionable wear of the parts or grinding of foreignmatter therein during the churning process. They are especially adaptedand intended for use during the process of working butter.

IIC

That I claim as my invention is 1. In a churn and butterworker, thecon1- bination of a revoluble drum, a U-shaped bracket l2 provided witha medial arbor journaled in the drum axially and with rollerbearingsadjacent to and at both sides of the arbor-axis, hopper-bar socketsadjacent to and radially beyond and above the rollerbearings, an dhopper-plate bearings adjacent to and radially beyond and above thehopperwhich said arbor is journaled concentrically with the drum.

3. The combination with a frame, of a revoluble drum supported thereon,said drum having at one end a substantially tight head and an enlargedannular drum-supporting gudgeon l1 thereon provided with a radialinwardly-extending flange, a centrally-disposed contracted tubularmember at a right angle to, and integral with, said flange, inserted inand partially through the head of the drum, and a gland securedreleasably to the flange at the outer end of the tubular member and soas therewith to form a stuffing-box about a journal therethrough.

In testimony whereof I affix my signature in presence of two witnesses.
